ElAttrache told ESPN Machado can hit, field ground balls and run. As he gains strength, he'll soon progress to baserunning, reactive defensive maneuvers and running out of the batter's box.

Machado tore his medial patellofemoral ligament in September and underwent surgery. Initially it was estimated he would need 4-6 months recorvery time, but January reports had him 6-8 weeks ahead of schedule.

The 21-year-old was a breakout star in his first full season for the Orioles in 2013. He won a Gold Glove Award and hit .283 with 14 home runs and 71 RBIs.
